How to do time sync via API

[serov]

Hi community!

Tell me please, how can I force time sync between VMs and host computer via API Vbox? Which method can I use?

Thank you in advance!

There isn't a method to do it AFAIK.
You can always fiddle with IMachine::setExtraData() and see relevant keys/values in User Manual - Topic 9.14 - Fine-tuning timers and time synchronization and see if you can force it by enabling/disabling or something like that.

Noteirak - thank you!

GuestAdd must be installed inside the VM for use IMachine::setExtraData() or we can use that method without guest add?

You don't need installed to use IMachine::setExtraData(), but you do need the guest additions installed for the whole timesync to have any effect.
